Based on the same flame-hardened bed as the more expensive 6300 Model the Clausing 5400 used less sophisticated ancillary equipment. As with other Clausing lathes, the lineage of this model can be traced back through the original  Model 100 (and the 6300 to the Model 200).
As standard the headstock was supplied with a hardened spindle, threaded 21/4" x 8 tpi, with the option of an L00 fitting at extra cost. A conventional tumble reverse mechanism was fitted to the changewheel drive and the gearbox was of the traditional Norton Quick-change pattern, with a single tumbler and open base, as fitted, for example, to early South Bend lathes.
Fitted as standard with a conventional V-belt drive countershaft unit mounted within the stand the  5400 could also be fitted with a sophisticated variable-speed drive unit identical in layout to that on the 6300. Unlike other contemporary Clausing lathes, the headstock drive pulley was placed between the bearings, not on the left-hand end of the spindle.
Giving ten spindle speeds between 35 and 1600 rpm the ordinary drive could also be equipped with a 2-speed motor that improved the range by giving twenty speeds from 17 to 1600 rpm - a rather better spread than that available from the 6300. The variable-speed drive unit of the 5400 spanned 35 to 1600 rpm, again superior to the 6300 with its 43 to 1300 rpm range.
The lathes illustrated below is fitted with the optional clutch and brake unit, the operating handle for which can be seen protruding from the face of the stand below the screwcutting gearbox..

Countershaft unit Model 5400
Whilst the variable speed drive on the 5400 was exactly the same as on the 6300,  the conventional drive was a simple 5 speed countershaft unit with over-centre tensioning. The unit pictured is fitted with the optional clutch/brake unit.
